l To all 'whom t 'may concern:

Be it known that-1,"SERo1 ODAASHIA'N,"

a citizen of the United VStates, residing at Voreester, in the oountyof Woreestergand State of lVIa-ssaehusettsjhave invented a -new and yuseful Boat, of which 4the "following Ais a specification.

This invention lrelates to a' boat and, particularly to certain novel .Y features "of oon-v struetionby means ofwhieh the continued operation' of lthe boat is rendered possible even after serious injury to portions thereof.

'In a -boat 'of'the'usual type, an injury below the water-line'is 'extremely serious, as repairs are diliieult and the continued operation of the boat ywithout repairs fis' 'commonly impossible or at least 1impractieable. I.

It `is the fgeneral obj ect of 'my cinventionv to provider a .boat in lwhich the rnainuor" b'o'dy portion of th'e :boat is rotatably "mounted so that an injured fporti'onthereof lvmayi'b'e readily movedto 1 a positio'n` above the wate'rline for rep'airs for'frem'o'val, `-whilealn unin* jured portion 1S .Simultaneously 'moye'd "be low 'the water-line in substitution for the injured portion. y

.A :further .object of fmy :invention vis Ito providea'fboat in fwhieh YEthe ipower 'plant ior' engine froom yis Amounted @in flixed position within-the rotatable bodywp'ortion, fand "is protected cfrom injury i'thereby. i

With these :general vobjects "in view', important features kof my inventionlrelatelto the 'eonstruc'tion of'th'e rotatable body member with isepar'ate -deta'ehable compartments whi'h may fbe "Jreadily' removed 'if desired, tof'tlefprovision of adequatek 'means ofeom- Inunioationv.between`` different parts of the boat, and to the provision fofvfisigna'lingde vices iby fwhi'ch 1 the vrlocation vlof 1an ury T'to the boat may ibe ipromptly vfas'e'e'rtained. l

My inventionv further relates .to certain arrangements :and Ieombi'n'ations lof Iparts which will vbe vhereinafter described and more V,particularly pointed lout 'in 4"the ap#- pended claims. j l

The preferred yformfofjln'yinvention and a `modification 'thereof 'are shown in the drawings in ,whiehy Figure 1 'is a plan .'fvie'w 'of farbjoatiembody# ingfthe preferred form f of my invention;

Fig. 2 .1i-s fa vertical longitudinal Als'eetgional View taken along the :li-ne :2;2 .in VYl;

. Fig. `21 is :a detail/sectioned 'i'liew v'tl-irongll secured to the opposite :ends of alarge'hllow Vshaft or i tube "12,A which entends foontinuously between the Afend sections. The sections Il0 and 1-1"are :alsoeonneeted by-:a' keel 13,flthe sections I Oland 11, the tube 512, and the ke'el' 13 forming' 'a single rigid f 'nitary structure'. i v i u 'An inner 'chamber or''operating-room"14` is liXed-on' the tube 12l near'li'tslongitudinal center. lAn fengine-forvmotor *175 "or -:other suitable "driving mechanism v is 'moun'ted in the Chamber 14', 4'which "ineehanism' may-'be o'o'nifleete'd` by a 'transmission shaft '16i to a propeller '117, the' shaft extending* diagonally alongfand faeross `the hollow tube 512. For eo'nvenien'ee of `opera'tion v"a corresponding shaft 16a andIpropellerli2L maylbe provided at-fthelopposi'te end fof the boat. V'Rudller's 18 and 18a are mountedatoppositeendsiof the "boat, 'which Aruk'vlders imay 'be operated by cables,- 19 extending :fal'onfg the hollow tube "l2 Ito the innerfehamber `vor @pei-ating roomilll. l u

Therparts thus ffar described i'are allf'xe'd with reference 'to "eaefh i other and freinainfin fixedV position 'during the Yoperation iefftlre boat.

The inner `chamber 14 is 'inelo'sed by' lthe inafin A"body'member of the 'boa't whieh conr-4 pri'see a shell 20 le''avimggan elllptealjlongitudinal fseeti'on 'and '-'rotatably mounted upon the hollowfs'ha'ft or v"tube :'12 on which supported by bearings '21 'and 22. lThe outer portion of the body fmemberA is v'rori'ned df separate Comp artmente 23 Vdeta'ehaloly fee; cured tothe'shell'lQO. As shown in fthe "djrawf in'g'e, veach compartment is vprovided v'with a lug or projection '24 extending ythrough 1an opening in the shell 20 between 'flangesfQ' and adapted yto Ibeheld in such position "by abolt26. y1t 'will be noted that the sh'ell20 is vspaced from the outer surfa'de of the ohanibe'r'll, thus providing a 'passage o r space I20 through which laccess .can be'had te fthe different heldingb'elte 2.6. The 'eempart'ments 23 fare formed 'with `curved sides and buter-'surfaces #se that 'they may more readily resist YVinjury from `blewshupon Athe outside thereof. This"r 'shape' of thedtaeh eef able sections leaves certain spaces between adjacent sections which may be closed by filling pieces 27 supported by the shell 20.

Any suitable provision may be made for rotating the shell 20 and the compartments supported thereby. l have herein shown a bevel gear 28 mounted upon a motor-driven shaft 29 and engaging a ring bevel gear 30 secured to the inner surface of the shell 20. l/Vith this construction it will be seen that the shell 20 and its supported compartments can be readily turned about the fixed shaft or tube 12 as an aXis, and .that an injured compartment can thus be readily: moved to the upper part of the circle, in which position it will beabove water and can be readily `repaired or removed.

VHand holds 31 may be secured to the outer side of each section so that they can be conveniently grasped from the outside if necessary. Projections 32 may also be placed on the outer surface of the chamber 14 which will enable persons to more readily pass along the space 20a between the chamber 14and the shell 20. A door or opening 33 is provided at the top of the chamber 14 through which access may be secured to the space 20a, and double doors 34 are provided from each compartment 23 to this space and also from each compartment to the neXt adjacent compartment. An opening 35 is also provided from` the chamber 14 to the hollow shaft or tube 12, and each end section may be subdivided into compartments 36 communicating with said tube.

In order that an injured compartment may be readily located I line the outer surface of each compartment with a thin metal covering 37 insulated therefrom but closely adjacent thereto, said covering being connected by a'wire 38 ,to a suitable signal drop in thechamber 14, the other side of the circuit being` completed through a ground connection to the frame. If the outer surface of a compartment is'perforated, as by a shot or shell, a short circuit will be caused between the outer surface of the compartment and the inner 'covering 37, and an indicating signal will thus be given in the chamber 14.

` The compartments 23 may be of considerable size, `and may be used for anydesired purpose, such as the transportation of merchandise or of passengers. At 23a in Figs. 1 and 3 I have indicated a special form of compartment designed for occupation by passengers. Inside `of this compartment there is provided a circular recess 40, to the outerV concave walls of which are secured circular tracks 41 upon which is supported an inner carrier 42, which is semi-circular in cross section and which, onA account of its weight, will always remain at the lowest portionof the recess 40. Rotation of the body member of the boat will therefore leave the occupants of the carrier 42 undisturbed.

ln Fig. 4 l vhave shown a slight modification of one of the end sections iin which the compartments 36 above the shaft are omitted andv a false cover 43 is provided to complete the conical surface of the en d section. This cover portion may be readily removed, and such removal facilitates the rdetaching of an end compartment Q3 should this become necessary.

Having` described the details of construction of my invention it will be seen that this construction localizes the effects of any injury tothe boat in such a manner that only a very general injury can interfere with the continued operation thereof. Furthermore, the operating,` mechanism is fully protected within the sectional body member and the continued- Aoperation of this mechanism is thus assured. V

Having thus described my invention it will be evident that other changes and modir fications can be made therein by those skilled in the art without departing` from the spirit and scope of my invention as set forth in the claims, and l do not wish to be otherwise limited to the details herein disclosed, but what I claim is Y 1. A. boat comprising end sections, a fixed hollow shaft securingsaid sections rigidly together, an inner chamber mountedin fixed position on said shaft, and a sectional outer casing' rotatably mounted on said shaft.
